2. 211/14/2015 Market’s View FACTS: –The SUCCESS of IEEE 802.16m relies on the success of WirelessMAN-OFDMA –The SUCCESS of WirelessMAN-OFDMA relies on more competitive WirelessMAN-OFDMA product LTE in the market: –Chunghwa Telecom (Taiwan): FDD with10+10MHz Downlink: 60Mbps @ 0km/hr and 10-40Mbps @ 80km/hr Uplink: 20Mbps without mobility @10MHz –TeliaSonera (Stockholm): FDD with 20+20MHz Average: DL: 33.4 Mbps and UL: 12.7 Mbps –……..

3. 311/14/2015 Lesson from these FACTs WiMAX Situation –10MHz TDD product only for current market Multi-carrier or wider bandwidth can be considered for 16e as well User will have different view of WiMAX due to multi-carrier or wider bandwidth

4. 411/14/2015 Market Timing Mature product of IEEE 802.16m is hard to be delivered by 2013 –Our experience told us Corrigendum requires some time –Field trial need operator to invest money –However, operator do not consider IEEE 802.16m if they can not return their investment from 16e network –Therefore, industrial investment will be postponed Conclusion: –Three to five years gap between 16e and 16m –16e enhancement can be filled in the gap and enhance the user experience of WiMAX and pave a path for the 16m

5. 511/14/2015 Benefits to Eco-system 16e Chip vendor –New product feature means higher profit chip –Higher profit invites more vendor joining 16e supply chain –16e can have more players 16e Base station vendor –Another business opportunity for base station upgradation –New product for high end market such as US, Japan and Taiwan

6. 611/14/2015 Another Issues in the Fields Inter-cell interference needs further improvement Power consumption of current 16e product Capacity and throughput need improvement, especially higher MIMO VoIP efficiency and capacity need improvement

7. 711/14/2015 Other Considerations Forward compatibility to 16m –The product should provide soft migration to 16m –Reduce protocol stack overhead –Reuse 16m mechanism Intermediate product between 16e and 16m –Project scope shall be minimized –One year is maximum

8. 811/14/2015 Conclusions Limited scope to one year 16m forward compatible enhancement Possible Features High Priority 1.Multi-carrier 2.20MHz review and supplement 3.Power saving enhancement 4.ICIC enhancement Low Priority 1.Co-existence (Implementation Issue) 2.VoIP enhancement 3.Higher layer MIMO and MU-MIMO
